Senior Program Architect - Governance, Risk, and Compliance

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.

We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.

Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.

Onebrief sells to defense and government customers. Those customers require proof, not promises, that our systems protect their data. We need a GRC Program Architect to inform and build the proof and keep it current as our compliance obligations grow.

This role owns the architecture behind our compliance posture. FedRAMP, CMMC, SOC 2, and international frameworks each impose different controls. Someone has to translate those requirements into systems, processes, and evidence that hold up under audit. That work falls to this person.

Compliance and security engineering can't operate as separate tracks here. Controls that exist only on paper don't protect anyone and don't survive an audit. This person will work hands-on with engineering to implement the technical controls that back up our compliance claims, not just document them after the fact.

The stakes are direct. A gap in our compliance program can block a contract, delay an authorization, or put customer data at risk. A strong program does the opposite. It opens doors to new customers and gives existing ones confidence to expand their use of our platform.
